c567307748 core: fix potential issue with header list init
If we're to receive some 500 headers (less than `headerBatchCount`) and quit
before receiving more of them we end up with clean `bc.headerList` that will
be inited going backwards to the `targetHash`, but code path doesn't add add
the `targetHash` itself which it should do in this particular case, otherwise
we end with no genesis block hash in the list.

d7f747fa9a network: wait for both Version messages before ACKing
Otherwise the node might crash in `startProtocol` because of missing Version
field in the peer. And it also keeps the sequence correct, Version MUST be
sent first and ACKs can only follow it.

c16c2bf102 core: store current header reference on clean init
Missing it the following line could fail on subsequent restarts:

        currHeaderHeight, currHeaderHash, err := storage.CurrentHeaderHeight(bc.store)

if the node was stopped before any headers had been received.

VM: Use JSON-based tests from neoVM

After the implementation of stack limits nothing is needed for us to pass reference JSON tests :)
The only thing that differs --- we do not compare stack in case of FAULT (which matches NEO 3 behavior).
Also two commits were reverted to match 2.x VM behavior.

7cf9a40468 network: fix MaxPeers, introduce AttemptConnPeers
Our node didn't respect the MaxPeers setting, fix it with a drop of random
connection when this limit is reached (to give a chance for newcomers to
communicate), but also introduce AttemptConnPeers setting to tune the number
of attempted connections.

This also raises the default MaxPeers for testnet/mainnet to 100, because
neo-go nodes love making friends.

ec76ed23a5 network: rework peer handshaking, fix #458
This allows to start handshaking from both client and server (mainnet/testnet
nodes were seen to not care about string ordering for it), but still maintains
some sane checks in the process. It also makes functions thread-safe because
we have two goroutines servicing read and write side of the Peer connection,
so they can clash on access to the struct fields.

Add a test for it also.

de2eeb4671 rpc: add one to the block height for the getblockcount response
There is a difference in interpretation of what a block count is. neo-go nodes
currently respond to this request with the latest block number which is the
same number that neoscan.io shows. However, C# nodes deliberately do add one
to this number when answering to the getblockcount request to account for the
genesis block number 0.

This patch makes us consistent with C# nodes wrt to getblockcount behaviour.

b46dd295bc rpc: add CORS workaround for RPC
This one enables our RPC to be called from the browser if there is a
need. It's insecure and not standards-compliant, thus this behaviour is
configurable is not enabled by default. It makes our node with this workaround
enabled compatible with neo-mon monitoring.

Originally debugged by @anatoly-bogatyrev in #464.
